What does it mean to put a knife under the Feng Shui bed?

The older generation said: a knife under the pillow can ward off evil spirits. I believe many people have heard the same thing, but it is not good to put the knife under the pillow, and there is no basis. Why do you say that?

First of all, it is harmful to your health. Putting a knife under the pillow is easy to hurt yourself when you sleep. For people with poor sleep, the sleeping posture is not good, and the quilt pillow is easy to fall off the bed. At this time, the knife placed under the pillow is easy to hurt yourself, ranging from cutting the face to stabbing the eyes and the temples, which is a serious problem. So generally speaking, try not to put the knife under the pillow.

Secondly, it is easy to have nightmares. Putting a knife under your pillow is easy to have nightmares, dreaming that your loved ones are gone, or you die unexpectedly, or you are chased by ghosts, and so on. I've heard too many examples. So it's really not good to put it under the pillow. Don't listen to some old people or others saying that pillows can be transported. If it is true, it is too simple! Believe in science, not superstition!
